RemoteCacheImpl contains reference to org.infinispan.query.dsl.Query, which is not always present on the classpath (it is an optional dependency). This prevents users from obtaining RemteCache by creating a bean:

@Bean
   public RemoteCache defaultCache(RemoteCacheManager remoteCacheManager) {
      return remoteCacheManager.getCache();
   }

In such a use case, Spring treats RemoteCache as its own bean and introspects it (scans all methods and fields and checks whether there are injection points or not). Once it hits Query it generates an exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultCache' defined in class path resource [hello/ApplicationConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.infinispan.client.hotrod.impl.RemoteCacheImpl] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@ba8a1dc]

In my opinion the best to improve the situation is to refactor RemoteCacheImpl code so that it doesn't contain optional dependencies.
